1. Initial Break‑In Period & First Change
- After first operation, internal components generate microscopic metal particles during run‑in phase.
- Hydraulic oil must be completely drained and replaced after the first 500 operating hours.
- Ensures early‑stage manufacturing debris is thoroughly flushed out of the system.
2. Standard Operating Cycle Recommendations
- Standard replacement interval: 1,000 to 1,500 operating hours after the initial break‑in.
- Under normal conditions, this translates to approximately once a year.
- Adhering to this schedule maintains optimal pressure, prevents valve blockages, and extends pump life.
3. Severe Duty & High‑Temperature Adjustments
- If running 24/7, processing abrasive scraps, or oil temperature consistently exceeds 60°C, degrade accelerates.
- Under heavy‑duty or high‑temperature conditions, oil should be changed every 3 to 6 months.
- Prevents oxidation and loss of lubricating properties.
4. Condition‑Based Monitoring & Immediate Replacement
- Regularly monitor oil condition: dark black color, acidic/burnt odor, or cloudiness indicates degradation.
- If oil turns dark, smells acidic, or becomes cloudy, replace immediately regardless of hours.
- Frequent filter clogging or drop in pressing force are clear signs requiring immediate oil change and tank cleaning.
